Solution Overview

Problem

Existing structural reinforcers often lack effective bonding across surfaces orthogonal to the longitudinal axis of structural members, limiting their reinforcement capabilities.

Innovation Solution

A reinforcer configuration with bonding material applied to both surfaces orthogonal to each other on a rigid carrier, allowing the material to bond with surfaces parallel and orthogonal to the structural member's longitudinal axis upon activation, enhancing the reinforcement strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If bonding material is only disposed on longitudinal walls of the carrier, then the manufacturing process is simple, but the reinforcement strength and structural stability are limited

Engineering Contradiction:
Improvereinforcement strengthVSAvoidbonding material configuration complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent transitions from bonding material applied only on longitudinal surfaces (1D linear distribution) to bonding material applied on both longitudinal and transverse surfaces (2D surface distribution). This dimensional expansion allows the bonding material to engage with multiple surfaces of the structural member simultaneously, creating a three-dimensional bond network that significantly enhances reinforcement strength while maintaining manufacturing simplicity through consistent application methods.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If bonding material is applied only on surfaces parallel to the longitudinal axis, then the application process is straightforward, but the structural stability and multi-axis bonding capability are insufficient

Engineering Contradiction:
Improvestructural stabilityVSAvoidbonding material application complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The bonding material configuration is designed to perform multiple functions simultaneously: it bonds to longitudinal surfaces to provide axial reinforcement, bonds to transverse surfaces to provide lateral stability, and creates inter-surface connections that resist multi-directional forces. This multi-functional bonding approach enhances structural stability without requiring separate bonding systems for different directions, maintaining ease of manufacture through a unified application process.

Inventive Principle:
Principle #6Universality (Multi-functionality)
